BigQuery is NoOps—there is no infrastructure to manage and you don't need a database. Python and Q execution times scale linearly with the size of the input table. BigQuery is less sensitive to the input table size. For tables larger than 200M rows, BigQuery becomes faster than Q. 0. The simplest way to approach this would be to load your dataset into a staging table into BigQuery using the load_table_from_dataframe method. example: client.load_table_from_dataframe (dataframe=df1, destination='project_id.dataset_id.updated_dataset') The result of the above will create a table. This article provides example of reading data from Google BigQuery as pandas DataFrame. Prerequisites. Refer to Pandas - Save DataFrame to BigQuery to understand the prerequisites to setup credential file and install pandas-gbq package. The permissions required for read from BigQuery is different from loading data into BigQuery; so please setup your service account permission accordingly.
